QLogic 2600 Series Hyper-V Virtual Server Engine - Manual (Page 15)

In Transaction-Intensive and Bandwidth-Intensive Environments
For virtualized environments, the most critical measure of performance is the ability to scale as the number
of VMs and application workloads increase. In testing conducted by QLogic, the QLogic QLE2672 delivered
three times the transactions and double the bandwidth of 8Gb Fibre Channel Adapters. The superior
performance of QLogic Gen 5 Fibre Channel Adapters translates to support for both higher VM density and
more demanding Tier-1 applications.
QLogic achieves superior performance by leveraging the advanced Gen 5 Fibre Channel and PCIe Gen3
specifications—while maintaining backwards compatibility with existing Fibre Channel networks. The unique
port-isolation architecture of the QLogic FlexSuite Adapters ensures data integrity, security, and
deterministic scalable performance to drive storage traffic at line rate across all ports.
More Virtual CPUs for Scaling Tier-1 Apps
If you’re concerned about hosting Tier-1 apps on VMs, the argument about virtualizing Tier-1 apps is over.
Even flagship enterprise applications such as Microsoft SQL Server 2012 and Exchange 2010 have adopted
server virtualization as a best practice. In fact, the CPU,
memory, storage, and networking requirements are
well documented by
Microsoft.
In the example on the right, a mission-critical OLTP
workload running on a single SQL Server 2012 VM
demonstrates linearly increasing transactional
performance and reduced transaction response times
as the number of virtual CPUs assigned to the
workload are increased to the maximum of 64 now
supported on Hyper-V.
Scalability with Gen 5 Fibre Channel
Throughput
Gen 5 offers a 3X bandwidth advantage and a 2X throughput
advantage over 8Gb Fibre Channel.
Virtual CPUs were increased from 4 to 64, increasing the
number of transactions per second. Hyper-V scaled
efficiently while decreasing the average response time.
